Eineetieation oi Letters Patent it known that We, Flinn lrzoiinu, a n 'the Uniteti residing et Brietoi, Bucks county, in tile Ste-te or Penn- Sylvania, and Louis I. SriLLi'no, n. citizen oi" the United Stetee, residing et Newark, ES- sex county, in the State of New ereey, have invented certain new en@ useful' improve niente in ifn/ouuin-Botties, of which the {oilowing is n fuii, cieer, and emot specitieetion.

@ur inef'ention reie'tes to improvements In Ineens for storing teorie, iieuie sind other fluids, and the seme has tor its object more pertiouieriy to provide n siinpie, eiiicient and reiiabie portebie receptecie by ineens; of which the contents of the receptacle muy be nminteinefi without niaterini change or tempeinture for eonsiderebie periods of time.

i'urther, said invention iles tor its object to provide e receptacie cioseti :it its bottom end adapted to receive an inner r eeptacie, and removably and jvieifiingiy support the seme in position therein.

Further, seid invention has for its object te provide e receptacle of the eherecter specitied having n removable top, and ineens for securing the saine in posit/on therein in order to maintain the inner vessel or recel`N teoie yieiriingiy in piece therein.

Further, seid inventi n hes for its object to provide reoeptecie ot the character specified, which ie so conetructecil that when the top is removed therefrom, inner reeepteeie wiii not `Foe suetcieniy projected out ot its easing.

To tile attainment oit the nfoi'eeziici obiects and ends, our invention consiste in the nov-ei.

deteiis of oonstrueeion ,end in the combinattion, Connection end arrangement of i erts hereinafter more uiiy fleseribed end then pointed out in the claim.

The top 1T is provided adjacent to its lower/edge with en annuler groove or recess 19, with which Communicate ey series of equally spaced vertical grooves 20, 2G haw ing their lower ende terminating at tile lower edge oi the @up 17, and their upper" ends merging with the annular groove or recess 1S). The annuler groove 19, and the vert-,ioni grooves 20, are of such size, entiso arranged, that tile seine Wiii. reefiiiy engage with any of the inwartiiy extending nrojeotions i6, it mijn-cent'- to the upper erige o? the casing i5 when seid top is inserted Within tile open upper enti of the casing l '21 denotes Cep removably disposed upon the nei; 'i8 ot the top l? which serves to incioee the receptneie, and the see,

in order to maintain the upper end 0i the inner receptacle 1 1, about the iunotion of the body with the neck portion 12 free from the top 17, a yielding packing 26 of" rubber or other suitable material in the form of a ring is disposed upon the upper end ofsaid inner receptacle 11, and surrounds the neck portion 12 thereof. In order to remove the inner receptacle 11 for the purpose of cleaning, or for any purpose whatever, it merely becomes necessary to rotate the top 17 sufficiently to bring the vertical grooves 20, 20 into register With the inwardly extending projections 16, 16 upon the" receptacle 15 whereupon the to may be Withdrawn from the casing 15, an access had to the interior of the receptacle 15. To secure the bottle in position again it merely becomes necessary to reverse the operation above described. It' will be noted that by reason of our improved construction, We are enabled to provide a vacuum receptacle comprising an outer casing and an inner receptacle so arranged relatively to eachother that When the outer receptacle 15 is grasped in one hand, and the top 17 in the other hand, and the latter rotated in order to disengage the same from said outer receptacle 15, the inner receptacle or bottle 11 cannot be projected out of its receptacle 15 owing to the fact that the top 17 can be maintained in engagement with the upper end of the inner receptacle 11 until the parts have been fully separated, and thus prevent the bottle being suddenly projected from the receptacle 15 andbroken by falling upon the floor, or

' striking any object in its path.

Having thus described our invention what We claim and desire to secure by Letters Patent, is:

A receptacle of the character described comprising a cylindrical outer casing closed receive said depending member, a coiled spring secured at one end to the under side of said cup and its .other end bearing against the closed bottom of said casing for yieldingly supporting the same Within said casing, a yielding packing disposed upon the upper end of said double-Walled receptacle and surrounding thev reduced neck portion thereof, and a top for said outer casing hav- 1ng an annular shoulder thereon, an annular recess below said shoulder, and a series or" vertical recesses having their upper ends communicating with said annular recess and their lower ends extending to the lovver edge of said top, said recesses being adapted to receive any of the projections arranged upon the upper end of said casing and permit of said annular recess being interlocked therewith to secure said parts together, and said double-Walled vessel in position Within said casing, substantially as specied.

Signed at the 'city of New York, in the county and State of New York, this 9th day of February, nineteen hundred and eleven.
